Cable Breakouts | Heat Shrink Cable Termination Breakouts – 3 Core Cables
Heat Shrink Cable Breakouts & Moulded Parts – 3M SKE 3-Way Cable Breakouts
Cable Breakouts
3M SKE 3-Way cable breakouts and 3M cable end caps are designed for quick and easy insulation and sealing of cable end or crutches, and provide resistance to abrasion, weathering and chemical attack.
Each heat shrink cable breakout will cover a wide range of sizes and different types of cables – also 4 core cable breakouts are also available.
These 3 core heat shrink cable breakouts are made from semi-rigid, cross-linked modified polyolefin material which is internally coated with hot melt adhesive. The materials used are zero halogen. On application of heat the adhesive melts and the part shrinks forming a perfect watertight seal – the 3 core cable breakouts can be used for insulating/sealing of cable crutches for indoor and outdoor applications.
Thorne & Derrick distribute complete range of cable terminations in both heat shrink and Cold Shrink for LV (Low Voltage), MV (Medium Voltage) and HV (High Voltage) cables and power systems.
